Appiieanon 'sied January ae, 1914. serial Nb. siasee.

Be it known that I, Friono CELESTINO SAC- oAGGIo, a citizen of theArgentine Republic, and resident of Talleres, Ferro Carril Sud,Argent-ina, vhave invented new and useful Improvements in Car-DoorHinges and Fasteners, of which the following is a specification.

rihis invention relates to hinges and means for securing the doors orhinged sides or ends of railway cars and other vehicles.

According to this invention the hinges of a vertically swinging door orthe like the straps of which hinges preferably extend frombelow'theb'ottorn of the door to'n'ear the top thereof are pivoted orhinged to the fra-me of the 'car and preferably to'a' bracket fixed tothe sole plate or s'oleb'ar or other appropriate part ofthe vehicle, towhich bracket or part is also hinged vor loosely co'nnected at a lowerlevel than the fiilcrum yof the hinge, one end of a 'strut orsupport'the other end of which is connected to the hinge strap or thedoorl in such ya manner as to allow both Vthe hinge andthe strutto turnfreely on their respective fulc'ra f'o'rop'eni'ng and closing purposeswithout jamming or locking, suitable locking means being also providedfor holding the said strut and with it the door in the upright or closedposition.

The locking means may operate automaticallyv to lock the strut duringthe last part of the closing movement of the door and preferablycomprises rotary cam which may also be operated by a lever.

In order that the invention may be easily understood reference is madeto the accompanying drawings in which Figure l is a vertical transversesection on the line II Fig. 2 of part ofa railway freight car with ayhinged or vertically swingingy door provided with a hinge and strutmade. according to this invention.

Fig. 2 is a side elevation'and Fig. 3 is a cross section of the hinge onthe line 'III-- IH, Fig. 2. Fig. 4 is an enlarged view of parts of thelocking or retaining device seen in Fig. ll. Fig. 5 isa front view ofFig.` l and an enlarged view of parts seen in Fig. 2. Fig. 6 isadiagrammatic end elevation of a railway car with the invention Vappliedthereto. Fig. 7 is a vertical transverse section of part of a railwaycarwith a modified construction of hinge and strut rand Fig. 8 is asideelevation of saine.

In carrying the invention into effect and as shown in Figs. l to y6, thebracket a is fixed to the outer vertical'face 0f the soleplate o whichmay be of wood or of steel of C section or of other appropriate sectionand the hinge strap c which as shown in Fig. 3 is suitably made LJshaped in cross section with lateral flanges d ,d is fixed or bolted tothe door@ vand hinged or pivoted .to the upper lug f on the bracket a..`The bracket is moreover provided with a horizontal flange 'gv whichtakes over and rests on the sole plate o.

The hinge strap c is suitably forked at the hinge end as indicatedby thedotted lines marked i inFig. 2 and is connected `'to Ithe hinge part orlug f on the upperpart of the bracket t by a pintle z', the said lug orhinge part f having a projection* or hooked portion 7e' (see also Figs.l, Land 5) which is cleared by the hinge when the door is swung downwardowing to the forked formation of the hinge. The lower part ofthebr'acket a; alsohas a hingepart or lug Z thereon and a bent strut mwith two flanges n; a is pivoted atits lower forked` end by a pin'tle oto the said lug Z and is disposed in front or outside of the hinge strap0. The axis ofy this pintle 0 suitably lies in the vertical planewhichcontains the axis of the pintle z' of ythe 'door hinge c, or the axis ofthestrut hinge may liein va vertical plane in front of the axis of thedoor hinge. The upperl part of the strut m is bent inward toward thedoor e andis suitably provided with twoinwardly projectingV lateral lugsp (Figs. 1,2 and 3) which loosely embrace the flanges Z on the upperpart of the hinge strap c, Asuch lugs .p being so constructed as toVInovefreely on the hinge strap c and without ,jamming against lthedoor. The strut is also slotted as at j to allow it topass over thehooklz. l i

The pintlespzl and o, von which .the door e and strut m are respectivelymounted, are at some distance from each other, ythe door when turnedupward or; downward describingan-arc such, as g (Figs. l and 6) whilethe strut describes an arc suchl as 1'. Consequently the connectionbetween the,Y door e andthe strut m must b e loose enough to permit thestrut to slide on the hinge strap c ai of Ithe door when the latter isbeing raised or lowered'. In order to lock the door in the closed orupright position the'flanges n of shown takes into the recess of theprojection or hooked member la' If the lever s be.

raised, Vthe semi-'cylindrical portion o revolves and passes out of therecess or hook 7s aforesaid so that when the strut is turned outward thesemicylindrical part o will clear the nose of the hook. Thusthe strut mand with it the door e is then free to be swung down to the openedposition of theV door seen in dotted lines in Fig. l. In this positionthe lever s hangs downwardly. When the door is raised for the purpose ofclosingV it, the leverremains'in a hanging down position for a time, butbefore the door reaches the upright or vertical position, the right-handside of the cam a comes into contact with the hook la whereupon, owingto the continued closing movement of the door, the cam together with thelever s is forced to turn on the trunnions t in a clockwise direction,so `that the lever assumes an elevated position and the cutaway portionof the hubu will allow the strut n, to pass over the hook, the hollowedside of the cam 'v meanwhile being adapted to roll over the point of thehook. As soon as the door reaches the vertical position and the struthas passed over the Vhook c the door will be automatically lockedbecause when the cam 'o has rolled to the inner side of the hook, suchcam will be released and the handle s will drop of its own accord andbring the *part o into the locking position shown clearly in Fig. 4. f Y

in Figs. 7 and 8, the strut is made of two double links w fw and :v andinstead of the strut being slidably connected to the hinge of the doore, it is hinged or pivoted to the lug .a on the part g/ of the doorhinge. The strut and the door are locked in position by a fastening suchas hereinbefore described, the trunnions t in thisl case serving as thehinge pins connecting the links w fw and .fr together the partsbeingsecured for example by washers 1 andi-pins 2.i Other appropriatefasteningsA or locking devices Vmay be employed however.

With slight modification the 'constructions hereinbefore described maybe adapted to the ends of wagons which may fold or fall inward insteadof outward.

What I claim is 1. The combination with thehinge'of a verticallyswinging carA door, of Ya strut hinged at one end to the wagon at somedistance from the fulcrum of the said hinge,

the otherjend of said strut being connected to the door in such manneras to allow'the hinge and strut to turn about their respec- Y -tive axesand means for holding said strut and with it the door in the closedposition. 2. The combination with the hinge of a vertically swinging cardoor, of a strutY hinged at one end to the wagon at some disy tancebeyond the axis of the said hinge,.the

other end of said strut being connected tothe door hinge in such amanner yas to allow the hinge and strut to turn about their respec-Vtive axes, a projection on the fixed part of the door hinge and lockingmeans mounted on the strut and adapted to engage with and be disengagedfromv said projection.

3. The combination with the hinge vof a vertically swinging car door, ofa strutl Vcam rotatably mounted onthestrut and adapted to be engagedwith and disengaged from said projection. Y

4f. The combination with the hinge of a vertically swinging car door,said hinge strut hinged at one endKV to the wagon 'at some distancebelow the axis of the door hinge, and slidably connected at thek otherend to the hinge in such a lmanner asv to allow fthe door and struttorturn simultaneously about their respective axes, a projection on thefixed part of the door hinge, a locking cam rotatably mountedY on thestrut and adapted to engage with said proe I jection,and a leverconnected with said cam Y According to a modification and as shown somedistance below the axis' of the'Y doorV hinge, the other end'ofsaidstrut having lugs, said'lugs loosely andslidably embracing the hingepart on the door in Vsuch a manner 'as to' allow the door and strutftoturn simultaneously about their respectiveY axes, a projection on thefixed'part of the door hinge, and a'locking c am'rvrotatably mounted onthe strut and adapted to engage with said projection. Y' I 6. Thecombination with the hinge of a izo vertically swinging car door, saidhinge comprisinga forked member pivotedto the xed hinge part on thewagon, of arigid strut hinged Yat one end tothe wagon at some distancebelow the axis of the door` 95 comprising a forked member pivoted to thefixed hinge part on the wagon, of a rigidV hinge, the other end of saidstrut having lugs, said lugs loosely and slidably embracingvthe hingepart on the door in such a manner as to allow the door and strut to turnsimultaneously about their respective axes, a projection on the iXedpart of the door hinge and a lever having a cam of semi-cylindrical andhollow form such lever being rotatably mounted on the strut for engagingthe cani with and disengaging it from said projection.

7. The combination with the hinge of a vertically swinging car door, ofa rigid strut having lateral flanges and hinged at one end to the wagonat some distance from and below the aXis of the door hinge, the otherend of said strut having lugs, said lugs loosely and slidably embracingthe hinge part on the door in such a manner as to allow the door andstrut to turn simultaneously about their respective aXes, a projectionon the iXed part of the door hinge and a lever having trunnions mountedin bearings in the flanges of the strut, a hollow semicylindrical camsituated between and connected with said trunnions and adapted to engagewith and be disengaged from the said projection.
